From 49c8de74eeb3b5a61f85bdeddd48a50e0376dc24 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sun, 7 Oct 2018 18:57:21 +0200 Subject: [PATCH] util/superiotool/smsc.c: Add SCH5504 register dump There is no datasheet available for this SuperIO, but dumping all possible registers on a Dell Optiplex GX520 resulted in data that was similar to other supported chips. Data also matches what is set in the BIOS, e.g. the parallel and serial ports' addresses.
